Thank you for your email and interest in Electrical Engineering & Computer Science at Northwestern.
The review process for MS applicants for Fall 2016 admission is underway and will continue until early June. The admission committee currently has over 1600 applications to review. Because of the size and diversity of the EECS department, admissions are managed by the research divisions rather than a central committee, so applicants in different areas will be hearing at different times. Unfortunately, we cannot be more specific about the decision timeline.
Your application was forwarded to the committee for review upon its completion. Decisions have yet to be rendered on nearly all applications submitted thus far. You still have some time to wait before hearing back, so please be patient.
You will receive an email once a decision has been made, but you are welcome to check the status of your application any time at https://gradstatus.northwestern.edu/
